Multiply the magnification of the eyepiece by the magnification of the objective lens to produce total magnification. For example, a 10X ocular lens and a 40X objective lens will produce a total magnification of 400X (10 x 40 = 400).
What is the total magnification of 40x?
| Magnification Total Magnification | Scanning 4x 40x | Low Power 10x 100x | High Power 40x 400x | Oil Immersion 100x 1000x |

What is the magnification of the specimen when looking at the 40x objective?
4x is a common magnification for scanning objectives and, when combined with the magnification power of a 10x eyepiece lens, a 4x scanning objective lens gives a total magnification of 40x.
What does 40x magnification mean?
It’s easy to understand. A 40x objective makes things appear 40 times larger than they actually are . ... The product of the objective magnification and the eyepiece magnification gives the final magnification of the microscope. So, a 60x objective and a 10x eyepiece gives a total magnification of 600x.
What would the total magnification of a specimen be if you were using the 40x objective lens on a compound light microscope?
To calculate the total magnification of the compound light microscope multiply the magnification power of the ocular lens by the power of the objective lens. For instance, a 10x ocular and a 40x objective would have a 400x total magnification. The highest total magnification for a compound light microscope is 1000x.
How is total magnification calculated?
Total Magnification: To figure the total magnification of an image that you are viewing through the microscope is really quite simple. To get the total magnification take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X .
What does 3x magnification mean?
This put simply means that any object you are attempting to focus on from 1” away would appear 10 times larger . The entire purpose as stated above is for the magnifier to deliver crisp focus and help you get a clear vision when focusing this close to the object.
What is the magnification power of the objective lenses?
| Objective lens X Ocular lens = Total magnification | For example: low power: (10X)(10X) = 100X | high dry: (40X)(10X) = 400X | oil immersion: (100X)(10X) = 1000X |

What are the 3 objective lenses on a microscope?
Essentially, objective lenses can be categorized in to three main categories based on their magnification power. These include: low magnification objectives (5x and 10x) intermediate magnification objectives (20x and 50x) and high magnification objectives (100x).
What three things change as you increase magnification?
This change alters the magnification of a specimen, the light intensity, area of the field of view, depth of field, working distance and resolution .
At what magnification can you see sperm?
The air-fixed, stained spermatozoa are observed under a bright-light microscope at 400x or 1000x magnification .
What is the highest magnification?
The highest magnification commonly used with the electron microscope is 200,000X .
What magnification do you need to see bacteria?
While some eucaryotes, such as protozoa, algae and yeast, can be seen at magnifications of 200X-400X, most bacteria can only be seen with 1000X magnification . This requires a 100X oil immersion objective and 10X eyepieces.. Even with a microscope, bacteria cannot be seen easily unless they are stained.
What can you see at 40x magnification?
At 40x magnification you will be able to see 5mm . At 100x magnification you will be able to see 2mm. At 400x magnification you will be able to see 0.45mm, or 450 microns. At 1000x magnification you will be able to see 0.180mm, or 180 microns.
What is the magnification of the eyepiece?
The eyepiece, located closest to the eye or sensor, projects and magnifies this real image and yields a virtual image of the object. Eyepieces typically produce an additional 10X magnification, but this can vary from 1X – 30X . Figure 1 illustrates the components of a compound microscope.
What can you see at 100x magnification?
At 100x magnification you will be able to see 2mm . At 400x magnification you will be able to see 0.45mm, or 450 microns. At 1000x magnification you will be able to see 0.180mm, or 180 microns.
